Tablet recommendations

Going to be doing some Android tablet development; want to buy a nice open machine for testing (and general use besides.) Google Nexus 10 is looking like it's going to be a nice device. Any other recommendations?

I haven't used the nexus tab, but I have the nexus phone and it's awesome. Considering the tab too will run jelly bean, I think it would be just as good.
My daughter has a Galaxy Tab 10.1 which is good too, but I think nexus would be a more advanced version
